SPECIFICATION forming part of Letters Patent No. 224,074, dated February 3, 1880. Application filed December 18, 1879.

' it pertains to make and use it, reference being had to the accompanying drawings, whicl form part of this specification.

My invention relates to an improvement in cultivators and it consists in the arrange ment and combination of parts whereby a light, cheap, and efficient fallow-cultivator is produced, as will be more fully described hereinafter.

Figure 1 is a side elevation of my invention with one wheel removed. Fig. 2 is a plan view of the same, and Figs. 3 and 4 are detail views.

(t represents the drivingwheels, and c the axle, whiolr is bent horizontally forward, as shown, and has the cultivator-beams (1 secured thereto. ,These beams are divided into two gangs, which are independently adjustable up and down, and all of the beams of each gang are rigidly secured together by the cross-braces 6, so that no one of the gang can be moved by itself.

The front end of each beam is formed into a hook, f, which catches under and around the axle,.and to. the,top of the front end of each beam is bolted the casting g, which has its end so shaped as to catch over the top of the axle, and, with the hook f, form a circle around it.

Each one of the blocks has a wing, 2', projecting from one or both sides, which wings are intended to bear against the rear side of the axle, and thus prevent the beam from havin g the slightest lateral play.

Upon the top of the center of the axle is secured the beam h, which is also braced in position by the two side braces j. Upon the top of this beam is secured the tongue I, the seat a, and the support 0.

Tothe ends of the axle 0, just inside of each driving-wheel, are secured the vertical sockets 1', which have the slots p through their innor sides, and along up the slots are marked suitable scales. In thesetwo sockets are held the ends of the rod 3, which has its ends turned downward at right angles, and which' ends can be adjusted up and down in the sockets, according to the depth it is desired that the shovels should run. Each end of the rod is held at any desired elevation by means of a set-screw, q and, in order to always have the ends at the same elevation, each one is provided with a marker, t, which extends through the slot in the socket, and shows exactly how high the end is.

By means of. this manner of adjusting the rod 8 at both ends the front ends of the beams are raised or lowered the same as the back ends, thereby keeping the beams level at any depth of furrow. The object is not to change the pitch of the teeth in adjusting for deep or shallow work, as there is only one proper pitch for the'teeth of a fallow-cultivator. j

The center of the rod is held in the support 0, and is immovable, While the ends are vertically adjustable, as described. Upon this rod are pivoted the two hand-levers 11, each one of which has a movable collar or box, u,on its short end, andupon which box are pivoted the rods to, which connect the lever with the gang.

By having the boxes movable and a series of holes through the end of the lever the boxes can be adjusted in and out from the center of motion, and thus adjust the depth'at whichthe shovels shall run.

By passing a pin through the box and lever the box can be rigidly locked in place.

Upon the top of each box is the ball as, which answers the place of a notch or tooth on the ratchet-disk in keeping the lever in an upright position. This makes a much more convenient arrangementthan to have a tooth to hold the lever upright, for where the ball is used it is not necessary to' push the lever to the side to disengage it from a tooth. When you wish to raise a gang you merely pull it straight down, which saves time and muscle.

Rigidly secured to the rod beside each lever isthe notched disk y, into the notches of which the lever is forced for the purpose of being held in any desired position by means of the coiled spring 2.

There is a stop on each ratchet-disk to hold the lever from going over past a perpendicular line, and the weight of the ball holds the leverfroin swingingback ofi" the center, thereby locking the gangs in the ground.

The driver, sitting on the seat, can raise or lower either one. or both gangs at pleasure.

Having thus described y invention, I claim- 1. The beams d, having the hooks f formed on their front ends to catch under and around the axle, in combination with the castings g, secured to the top ofthe beam and catching over the top of the axle, substantially as shown.

2. The combination of the axle 0, rod 8, sockets r, levers v, and gangs, substantially 'as specified.

3. The combination of the levers v and adjustable boxes at with the connecting-rods to, substantially as shown.

4:. The combination of the levers 11, boxes u, 20 provided with the weights or balls as, moving thereon, and connecting-rods to, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 3d day of 25 December, 1879.

CHARLES 1 CARTER.
